Hey everyone, I'm not sure if anyone has heard of this website (labex.io) before, but I just started using it for about hour today to learn. You can learn Linux, DevOps, Cybersecurity, and many more with Hands-on Labs Develop skills in Linux, DevOps, Cybersecurity, Programming, Data Science, and more through interactive labs and real-world projects. It's pretty much all hands-on activities and even has plenty of learning paths and projects that you can build (free). This is also kid friendly too.
